10 Claims.

The invention relates generally to harvester threshers of the folding type and particularly to an improved combination grain and caster wheel assembly for supportingthe grainward end of the harvester part in the cutting and folded transport positions thereof.

The object of the invention is to provide an improved, simplified wheel assembly of the type mentioned which is fixed against castering in the grain cutting position of the harvester, and which wheel can be released for free castering movement when the harvester is in its folded, trailing, transport position, said wheel always being in supporting relation to the free end of the harvester part.

This object is briefly achieved by locating an arm on the free end of the harvester axle, the end of said arm providing a pivot point for a yoke member which carries a pin in turn carrying the wheel. Said Wheel has an offset hub and bowed out spokes to permit locating the pivot point end of the arm inside the periphery of the wheel tire and on a central vertical plane passed through the wheel. Such location of this pivot point permits the wheel inits released position to caster freely.

In the drawing showing a practicable form of the invention:

Figure l is a plan View of so much of a harvester thresher as is necessary to show the wheel assembly, said wheel shown in grain cutting position of the harvester in full lines; and, in the dotted lines, showing the harvester and wheel in the folded transport position;

Figure 2 is a side elevational View of the wheel assembly, looking from its stubbleward side; and,

Figure 3 is a plan view showing a horizontal, central sectional view through the wheel.

These combination wheels are used with harvester threshershaving a thresher part 10 carried on an axle 11 and a pair of wheels, only one of which is shown at l2. The grainward end of the axle 11, grainwardly of the wheel 12, has connected to it by a two-way hinge 13, fa normally transverse harvester support or vaxle 14, said hinge permitting iioating or oscillatory movement of the axle 14 to conform to ground contour, and folding movement rearwardly and horizontally to narrow the overall width of the machine for transport through narrow places, in a manner well understood in this art. A harvester header platform part is shown at 15 supported in the usual way by the support 14. The

grainward end of the support 14 is carried by the improved wheel assembly of this invention now to be described.

The grainward end of the support 14 has fixed to it a sleeve or bracket 16 including a forwardly and outwardly extending arm 17 carrying at its free, bifurcated end, a vertically disposed pin 1S, to which pin the front end of a longitudinally and rearwardly extending yoke member i9 is pivotally connected. The rear end of the yoke terminates in a cross-sleeve portion 20 in which is turnably carried a short wheel axle or pin 2l including a hub 22 clamped to its outer end by a nut 23. The hub carries spokes 24 in turn carrying the wheel tire 25. A sleeve 26 is pinned to the opposite end of the axle 21 to hold the axle properly in the sleeve 20, and a dust proof cap 27 closes the axle end assembly, as shown. The wheel is of the dished type having an offset hub, the load, however, being properly distributed on the bearing or axle 21.

The sleeve 16 hingedly carries at its rear side a latch pin 28 cooperating with a slotted bracket 29 formed on the rear of the sleeve 2i), so that, by means of a nut 30, the wheel 25 can be secured or latched to the sleeve 16, to make the pivot 18 inactive and thereby look said wheel against castering, but permitting it to turn or roll.

In use, in cutting grain, the platform 15 and support 14 are in the transverse cutting position shown in the full lines in Figure l. The wheel 25 is latched by pin 28 against castering in the manner described, because in the grain cutting position it is preferable that the wheel does not caster. When it is desired to transport the machine over a road from one field to another, then the harvester part is folded alongside the thresher part by swinging the support i4 about its hinge i3 to the dotted line position of the parts shown in Figure 1. First, however, before so folding the parts, the latch 28 is released to free the Wheel, so that, as the support 14 is folded, the wheel 25 casters to form a rolling support for carrying the harvester part to its folded position. As the machine thereafter is drawn forwardly, the wheel 25 assumes a trailing, castering position, as shown in dotted lines in Figure 1, with the pivot point 18 located within the periphery of the wheel, thus permitting the greatest possible freedom of castering for such a compact wheel assembly. Further, in the cutting position of the wheel, its is in line with the axis of the support 14.

This pivot point location has the advantage of permitting the wheel to caster without tilting the wheel as is necessary when the pivot point is out side and laterally of the wheel.

From this disclosure it will now be seen that an improved, compact combination wheel assembly has been provided, having outstanding advantages.

It is the intention to cover changes and modications not materially departing from the spirit and scope of the invention as indicatedbythefollowing claims.
